Should the TV wall be full cabinets or a feature wall?

That depends on your actual needs. Full cabinets do provide plenty of storage, but covering the entire wall with cabinets can easily feel oppressive, especially if the living room depth is insufficient. A feature wall feels more breathable, but storage is reduced. A compromise is partial full cabinets plus open shelves, so it doesn't feel visually blocked. TV cabinets are calculated by projected area; mainstream pricing is 400–800 yuan/㎡ in Beijing and 340–680 yuan/㎡ in Baoding, Langfang, Xiong'an and Zhuozhou, depending on the design and hardware. During measurement, we first confirm wall flatness and internal/external corners, then decide the finishing method. The above are reference prices and do not constitute a formal quotation; the actual price must be calculated based on dimensions, design, materials, hardware, quantity, and on-site conditions.
